> Certainly you wouldn't want to slam the brakes for a plastic bag floating in the wind. Maybe not )slam_ but if I am not confident what's the thing on the road ahead of me, I slow down. At night, when oncoming traffic can blind me, I slow down to give the driver (me) time to react. Otherwise if hitting obstacles is acceptable anyone can create a self driving vehicle.
